Built from high speed steel with a bright uncoated finish, this bit features a standard 118-degree split-point tip and a two-flute regular spiral configuration. The straight-cylindrical shank measures 25\/64 inches in diameter, matching the bit diameter for consistent chuck grip. With an overall length of 5.125 inches and a flute length of 3.75 inches, it delivers adequate chip clearance for drilling through cast iron and steel. Installation is performed by machinists, maintenance technicians, and trade professionals working with left-hand extraction or reverse-rotation setups.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling cast iron and steel in both shop and field environments. Left-hand cut geometry makes it particularly useful when working with broken fasteners, studs, or bolts — the reverse rotation can back out a fastener while drilling, eliminating the need for a separate extractor in many situations. The Series 150L designation places it in a general-purpose performance tier appropriate for standard drill presses, hand drills, and reversible power tools operating in reverse. It is sold individually with a minimum order quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cutting direction for broken fastener extraction and reverse-rotation drilling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with bright uncoated finish for general-purpose use in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web configuration for reduced entry force\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, two-flute design promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank accepts standard three-jaw chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of -0.0010 to 0.0000 inches ensures consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard reversible drill presses and hand-held power tools with three-jaw chucks.

When using for broken fastener extraction, confirm the drill and driver are set to reverse rotation before applying cutting pressure. Wear appropriate eye protection and secure the workpiece to prevent movement during drilling. Inspect the cutting edges for wear before each use and replace the bit if chipping or dullness is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 25\/64 inches (0.3906 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1232 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 44425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51733699592498,"sku":"44425","price":31.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fbdb371bde269b04457faa2764be38a6.jpg?v=1788758448","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44425-jobber-length-drill-bit-25-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
